I was using a PB9.0 + SQL2005 can you tell me how to do the database in used three layer architecture, can speed up the operation

CodePudding user response:

Then add a layer, have to modify the code!
Amount of workload and maintenance than C/S point many, very trouble!

CodePudding user response:

Add a layer, the database connection and pick up the data on the middle tier to achieve

Also can put some business logic on the middle tier

CodePudding user response:

Three layer is usually slow down

CodePudding user response:

I now using pb9 + sql2000, or two layers of small units, two layers of personally think that will be enough, if three layers, PB there is no good program, said online EASERVER is too expensive, with people, also is not so stable, out of the question, can not solve, so I don't have, including my used SQLANYWHERE database, have developed a small inventory management system, sometimes appear some problems, to BAIDU search, information is too little, so now I wouldn't have SQLANYWHERE database, ha ha
